A TXT record is text in free, human-readable form, that's associated with a domain name as a DNS record for one purpose or other. The most frequent use of a TXT record is to add your site to a search engine or to an analytics platform, which offers details about the traffic to your web site. Setting up this kind of a record works as proof that you're the domain owner and they will supply the content that you should include as the value when you create the record. Another purpose of a TXT record is to verify that an e-mail message is sent by the domain owner and from a trusted web server - this is the so-called SPF protection, which helps prevent any electronic address set up under your domain to be forged and unauthorized people to send junk e-mail making it look like it was sent from your own mailbox. You can include any other info you want to be associated with your domain in a TXT record as well.
